Well perhaps I won't change too much. I'm not even sure if I will really change anything yet. Quality certainly isn't an issue, but maybe the bitrate could be slightly more tuned. I'm going to encode a few more albums with this mode today and test what kind of averages I get. I'd like to shoot for a 256kbps average if possible (which as you say, it may already be reaching.. at least some of my data seems to indicate this as well).

So I won't really change anything unless I'm sure there is a need to, so far there probably isn't.
